Relieve my anxiety please!!!

I am having a 2nd interview with the hospital so I am assuming that the Doctor's office really liked me and want me to join their team. Anyway, the hospital called and my 2nd interview is on tuesday and she said I have an hour long medication exam. I am stressing about the littliest things right now. I just need someone to let me know what you get for these questions since Math is not my strong point.

1. 250/200 = x/1
2. 8/4
3. 1.00 / 3
4. 1/5 = x/100
5. 60/90 = x/2
6. 0.9 x 0.9
7. 2.25 + 3.55
8. 250/1 = x/2

I would really appreciate any input you can give. I have completed the questions but I just want to confirm if I am right with somebody...........anybody!!!
